HEH :-)
I used something similar for ages. In fact, I still have it in my
.screenrc file, but commented out:
caption always "%{= kf}%5n %t (%H) %=%Y-%m-%d %c:%s "

This is a job for GNU Screen!
Actually, this is the least of screen's abilities, but it does give you
exactly what you want (plus more!) and it doesn't depend on what shell
or other program you are running in the terminal.
1. Install GNU Screen ( /usr/ports/misc/screen )
2. Create ~/.screenrc containing the following:
# Delta applied to /usr/local/etc/screenrc
startup_message off
escape ^\\\
defscrollback 2048
hardstatus on
hardstatus alwayslastline
hardstatus string "%{.bW}%-w%{.rW}%n %t%{-}%+w %=%{..G} %H %{..Y} %Y/%m/%d
%0c:%s "
nethack on
msgwait 1
msgminwait 1
Most of this is optional; these are the settings I use. The most
important thing for the ticking clock are the hardstatus lines; the
longest has almost certainly wrapped.
3. Now when you log in, your first command should be something like:
screen -S main -xRR
( man screen for alternative approaches )
Now use your computer as you ordinarily would. You'll have to 'exit'
twice to log out; the first exits screen and the second exits the
spawning shell.
Or, you can:
4. Run screen automagically in every interactive shell.
How exactly to do this depends on your shell and other configuration;
I do it by putting the following at the very end of my .zshrc ( I use
the Z Shell, and have no .zlogin or .zlogout ):
if [ ! $TERM = "screen" ]; then
exec screen -S main -xRR
fi
Now screen is login-shelly; it runs automagically in every terminal
session and you will automagically be logged out when screen exits.
There are implications to having it run this way (take note of the
'exec' above). Anyway, there are heaps of information available
regarding screen, google for 'gnu screen' to find it.

Re: This is a cool shell prompt question
May be, you can use some small shell script to run as getty replacement ? It must open tty and start the clocks on it. It even will be automatically restarted if needed by init process.

Depending on which shell you're using, I'd say yes, since just about anything is possible under Unix. :-) However, how to do this is not immediately obvious to me. Sorry. :-) Might be a good question for the comp.unix.shell newsgroup. Some serious shell gurus hanging out over there, and they always rise to a good challenge. :-) If you do find out anything, a followup here would be nice. Thanks! -- Conrad J.
